The California Department of Toxic Substances Control(DTSC) released proposed regulations, which “establish performance goals for the collection and recycling of used thermostats containing toxic mercury,” according to a DTSC press release. In 2006 California banned the sale of new mercury-added thermostats, but there are still millions of them in use. These regulations would require manufactures to collect and recycle over 65,000 mercury containing thermostats in 2013. Recycling goals would increase until 2017, when the state would have a goal of 75% collection and recycling rate, which would be an estimated 147,000 thermostats. As part of the proposed regulations, manufacturers who formerly sold mercury thermostats would be required to meet the recycling goals of the Thermostat Recycling Corporation(TRC), either through participation or joining a similar program.

The DTSC will hold a hearing on October 2, 2012 at the Cal/EPA Building in Sacramento, CA. Written comments must be submitted to the DTSC by no later than 5:00 p.m. on October 2, 2012.
